Silk
By. Carri Burkett Period 7 Biology
Silk is a natural fiber , parts of the silk can be woven into materials - actually its not so simple to get silk to make silk you need silk worms .
Silk worms come from moths that are indeginous to China . Bombyx mori is a domesticated variety bred from the Bombyx mandarina species from northern India to northern China, Korea, Japan and eastern Russia.
As hinted by its Latin name, the Silkworm loves white mulberry leaves, but it will settle for the leaves of the Osage Orange or the Tree of Heaven found in China. ( picture found on google images )
These days, the silkworm is dependent on humans for reproduction and eggs take about ten days to hatch.
A single from a
silkworm cocoon can be about half a mile in length, if carefully unraveled.
The general rule of thumb is that 10 pounds of mulberry leaves can feed 200 worms that will spin a pound of cocoons that will make about 100 miles of the very thin thread.

DNA
This is a regular DNA cell it includes the sugar and phosphate groups with the adenine & thymine together which
is colored adenine orange & thymine yellow , then with the others i have cytocine & guenine which is colored cytocine
green & guenine purple. Along with the red phosphates & blue sugars the DNA cell i colored gray.
In this picture the DNA cell is unwinding which is like it is loosing cells for example its like the molecules are falling
off as they unwind.
The DNA strand is winding pack up and is getting a new strand and is getting more molecules back.
This DNA strand is done winding back up and when it is done winding back up it forms 2 strands. ( when i took the picture it only captured One DNA strand. - my apologizes.)
Vocabulary:
1.telomeres - telomere is a region of repetitive DNA at the end of a chromosome, which protects the end of the chromosome from deterioration.
2.okazaki fragments- short fragment of DNA created on the lagging strand during DNA replication.
3.dna ligase-n molecular biology, DNA ligase is a special type of ligase that can link together two DNA strands that have double-strand.
4.telomerase-an enzyme in eukaryotic cells that can add telomeres to the ends of chromosomes after they divide.
5.cancer-is a class of diseases in which a group of cells display uncontrolled growth.
6.transplanted cells -the product in a cell is removed then put back inside it.
7.cloning- the cell is copied.
8.aging- happens when the cell is dying.
